Double balloon enteroscopy has a limitation for positioning an enteral stent in the distal jejunum through its long, narrow biopsy channel. When the distal end of its overtube is left in place close to the neoplasia with the enteroscope removed, if we push an enteral stent introduction system, it tends to form loops so the techniquecannot be performed with this instrument. However, the double balloon colonoscope has a shorter overtube length and using the same push-and-pull technique we can reach the distal jejunum with this instrument by inserting the delivery stent system without loops through its overtube. We present a patient with neoplastic obstruction in the distal jejunum with resolution of his symptoms after positioning an enteral stent.
